Al Messerschmidt/Getty ImagesAnthony Jennings' ability as a running quarterback will be a weapon LSU can utilize this fall.

1. Those QBs can move: Having seen Anthony Jennings play a bit as a freshman, we already knew he had some wiggle. But freshman Brandon Harris looks to be at least his equal in the running-quarterback department after he had 76 rushing yards and a touchdown in last Saturday’s spring game.

Whichever quarterback wins the starting job, it’s a certainty that his playing style will differ wildly from predecessor Zach Mettenberger, who stood like a stone in the pocket. With either Jennings or Harris under center, defenses will have to respect that he can take off and make big plays with his legs.

“Oh boy, isn’t that fun to see?” Miles asked, referring to a 41-yard run that Harris made in the second quarter. “You go back in there and the defense makes a mistake and let me tell you what happened: One of those linebackers went over there to the other side with one of those backs and did not stay home. And so that quarterback came out the back side and suddenly 41 yards later, he’s run out of bounds.

“That’s something you can’t do, either, so when you line up against a quarterback with that kind of ability -- and both of our guys have it -- you’d better keep that linebacker home.”

Jennings still seems to have a tendency to hold on to the ball too long while looking to pass. Iowa sacked him four times in the Outback Bowl, and his defensive teammates got to him four times in the spring game. Harris seemed to have a better idea when to tuck it and run, which doesn’t seem to be a terrible idea for either of them, as they can both be dynamic runners when they leave the pocket.

2. Linebackers will be strong: Saturday was a great day for LSU’s linebackers. Not only did Kwon Alexander and Deion Jones both intercept Jennings' passes and take them to the house for touchdowns, but Ronnie Feist (14 tackles) and Lamar Louis (seven tackles, 0.5 tackle for a loss) were their respective teams’ leading tacklers.

Feist seemed to be everywhere, continuing what Miles said was an impressive spring from a physicality standpoint.

“When he hits you, you’re hit,” Miles said of Feist. “There’s no pretend to it.”

Senior middle linebacker D.J. Welter apparently left a major impression on his coaches this spring as well. Not only was he among the defense’s honorees in awards for leadership and for outstanding performance, but he was the lone winner of the Jimmy Taylor Award, the team’s comprehensive spring award for outstanding leadership, effort and performance.

3. Offensive playmakers still must emerge: It seemed like a foregone conclusion even before spring practice started that some of the team’s top offensive players for 2014 weren’t on campus yet. Spring didn’t do much to change that perception.

Kenny Hilliard and Terrence Magee -- who dealt with a sprained ankle for much of the spring -- were adequate at tailback, but freshman Leonard Fournette will inject some star power to the position once he arrives on campus. Likewise, Malachi Dupre, Trey Quinn and the new receivers will add explosiveness at a position that was riddled with injuries throughout the spring. The receivers were nearly nonexistent in the spring game.

LSU wide receivers totaled seven catches for 200 yards and two touchdowns on Saturday. Sounds pretty good, right? But five of the catches, 130 yards and both touchdowns came from one player: Travin Dural.

Otherwise, the group frequently dropped passes and misplayed catchable balls, proving that they need every bit of the available practice time this summer to develop chemistry with their quarterbacks. Dural looks like a star in the making, but the others have a lot to prove from a consistency standpoint.

4. Tight end talk seems legit:DeSean Smith and the Tigers’ other tight ends expressed hope this spring that they would get more opportunities to catch passes in 2014 than they did last season, when wideouts Jarvis Landry and Odell Beckham got most of the looks from Mettenberger.

They said that’s how things had been going in practice, and Saturday looked to continue that trend. Smith led the way with three catches for 45 yards and a touchdown, but Dillon Gordon (2-32), Logan Stokes (1-26), John David Moore (1-20) and Travis Dickson (1-8) also made receptions. In all, the tight ends accounted for eight of the Tigers’ 21 catches in the final spring scrimmage, and offensive coordinator Cam Cameron seems pleased with the weapons he has at his disposal at the position.

“Every year, with different personnel, creates a whole new set of opportunities, and I think the opportunities for our tight ends are going to be critical,” Cameron said. “I was thrilled -- for the most part -- I thought they made the most of it.”

5. Defense is on the comeback: Judging by the way the White team (which featured the starters) throttled the Purple team’s offense on Saturday, it looks like LSU’s first-team defense has the potential to rank among the SEC’s best this fall.

The Purple team accounted for 179 yards of offense on 46 plays -- 53 rushing on 27 carries and 126 passing on 6-for-19 attempts. The Purple converted for a first down just once out of 11 third downs.

After saying earlier in the week that he overthought things in his first season as a starter, defensive end Danielle Hunter seems to have cut loose now. He recorded two sacks on Saturday and was a regular presence in the Purple team’s backfield.

He was only one member of a sizable group of defensive players on both teams who flashed major potential in the scrimmage. Things seem to be looking up for defensive coordinator John Chavis’ bunch.
